Abstract

The invention discloses a multi-band frequency spectrum aggregating wireless transmitter-receiver device which is characterized in that multi-band simulating radio frequency front ends are aggregated; different radio frequencies are divided into 20 MHz and 60 MHz processing frequency bands; analog-to-digital conversion while receiving a base-band signal and digital-to-analogue conversion while sending are performed in low and intermediate frequencies; and a signal treatment relative to a base-band NC-OFDM modulation-demodulation is performed by a sending base-band processing channel and a receiving base-band processing channel which are dynamically arranged. The invention solves the problem that the prior mobile communication terminal cannot work in multi-band at the same time during the communication process and only can use continuous frequency spectrums. The frequency spectrum aggregating function of the transmitter-receiver device realizes a data rate required by an IMT-Advanced system.

Description

technical field

[0001] The invention belongs to the technical field of wireless transmission and reception for digital information transmission, and in particular relates to a wireless transceiver device for organizing spectrum fragments on multiple frequency bands in a wireless mobile communication system to realize spectrum aggregation. Background technique

[0002] International Advanced Mobile Telecommunications (IMT-Advanced) is a new generation of mobile communication technology defined by the International Telecommunication Union (ITU). It is a new development of 3G technology, and it includes mobile systems with new capabilities beyond IMT-2000. According to Recommendation ITU-RM.1645 "Framework and Overall Goals for Future Deployment of IMT-2000 and Post-IMT-2000 Systems", the design goal of the data rate of the IMT-Advanced system is to support 1Gbps data services when the user is stationary or moving at a low speed Rate; when the user is in a high-speed mobile sta...
